Automotive machining requires different cutting materials for hardened transmission parts, cast-iron brake and engine components, and high-volume aluminum housings. Huamin Tools supplies CBN, ceramic and PCD inserts for hard turning, cast-iron machining and non-ferrous finishing, with grade selection based on material, hardness, interruption, surface finish and production volume.
| Component | Typical material | Operation | Starting tool direction |
|---|---|---|---|
| Gears and shafts | Hardened steel | Finishing after heat treatment | CBN inserts |
| Bearing rings | Bearing steel | Hard turning | CBN inserts |
| Brake discs and flywheels | Gray cast iron | High-speed turning | Ceramic or CBN inserts |
| Cylinder liners and exhaust parts | Cast iron | Semi-finishing and finishing | Ceramic inserts |
| Engine blocks and housings | Aluminum alloy | Precision finishing | PCD inserts |
| Pistons and wheels | High-silicon aluminum | High-volume finishing | Wear-resistant PCD |
Final selection should be confirmed with the actual material grade, hardness, casting condition, interruption level, machine rigidity, coolant strategy and required surface finish.
